saving the device name is a nice functionalities. it's just that the 2nd card name should be :
"USB audio CODEC #2"

i tried this :
http://www.alsa-project.org/main/index.php/Asoundrc#Virtual_multi_channel_devices
i was successfully using the "multi" device with aplay, but not with pd.

the easiest solution i found is to use pd 0.45, since -audiodev 5 is really opening the device 5.

so, for information, i have 3 pd running each on a different soundcard (2 are usb), in order to have 6 output on a Raspberry Pi.
synchronisation between sound card is not sample accurate, but it's ok for now.

using 1 pd with multiple out device did not work : a sound to dac 1 is sending sound to all 3 devices.


thanks and Cheers
